An Act amending Title 29 (Federal Relations) of the Pennsylvania Consolidated Statutes, providing for immigration preemption and cooperation; and establishing the Immigration Cooperation Fund.

HB 403 preempts Pennsylvania municipalities from adopting policies that block law enforcement cooperation with federal immigration enforcement. It prohibits local governments from restricting officers from complying with federal immigration requests, assisting ICE, allowing ICE access to county jails, inquiring about immigration status of people in custody, or sharing release information. The bill establishes an "Immigration Cooperation Fund" to support this cooperation, though specific funding mechanisms are not detailed in the provided text. This directly affects all Pennsylvania cities, towns, counties, and their law enforcement officers, judicial staff, and correctional personnel.
